A magazine cover on the Women's March on Washington made a major error, and Twitter is flipping out

• Express magazine published a cover story about the Women's March on Washington.• They used the male symbol instead of the female symbol on the cover.• Twitter mocked them relentlessly.• Express issued a different cover with the female symbol.

Express Magazine, published by The Washington Post, wrote a story about this soon-to-be historic event, and tweeted out their magazine cover. Can you spot the mistake they made?

There's something off about this. Express magazine/Twitter

The cover illustration features women arranged in the form of a Mars symbol,♂ , which represents men, instead of the Venus symbol, ♀, for women. (They also spelled "Today's" as "Today'a" in the tweet.)

The magazine already published the cover in print. It's been "put out at newsstands across D.C." this morning, according to Kimberly Betsill, who picked up a copy.

Express deleted the tweet and apologized, misspelling "erroneously" in the process.
